yes，sir，let us use the imgFilePath jpgs to avi file，such as

function Images2Video(imgFilePath, filename_out)
if nargin < 2
    imgFilePath = fullfile(pwd, 'david\img');
    filename_out = fullfile(pwd, 'out.avi');
end
% 清理空间
clc;
% 起始帧
startnum = 1;
% 默认结束帧为jpg图像数目
endnum = size(ls(fullfile(imgFilePath, '*.jpg')), 1);
% 创建对象句柄
writerObj = VideoWriter(filename_out);
% 设置帧率
writerObj.FrameRate = 24;
% 开始打开
open(writerObj);
% 进度条
h = waitbar(0, '', 'Name', 'Write Video File...');
% 总帧数
steps = endnum - startnum;
for num = startnum : endnum
    % 当前序号的名称
    file = sprintf('%04d.jpg', num);
    % 当前序号的位置
    file = fullfile(imgFilePath, file);
    % 读取
    frame = imread(file);
    % 转化为帧对象
    frame = im2frame(frame);
    % 写出
    writeVideo(writerObj,frame);
    % 刷新
    pause(0.01);
    % 进度
    step = num - startnum;
    % 显示进度条
    waitbar(step/steps, h, sprintf('Process：%d%%', round(step/steps*100)));
end
% 关闭句柄
close(writerObj);
% 关闭进度条
close(h);
